This example shows how to use the report viewer events. Some viewer actions have events to which you can subscribe. For example, print action, begin of the export, design report:
<script type="text/javascript">
// Enable the design button
var options = new Stimulsoft.Viewer.StiViewerOptions();
options.toolbar.showDesignButton = true;
// Create the report viewer
var viewer = new Stimulsoft.Viewer.StiViewer(options, "StiViewer", false);
// Assign the onGetReportData event function
viewer.onBeginProcessData = function (args) {
var ds = new Stimulsoft.System.Data.DataSet("Demo");
ds.readJsonFile("../reports/Demo.json");
args.report.regData("Demo", "Demo", ds);
}
// Assign the onPrintReport event function
viewer.onPrintReport = function (args) {
}
// Assign the onBeginExportReport event function
viewer.onBeginExportReport = function (args) {
switch (args.format) {
case "Html":
args.settings.zoom = 2; // Set HTML zoom factor to 200%
break;
}
}
// Assign the onReportDesign event function
viewer.onDesignReport = function (args) {
alert("Design button presed.");
}
// Create a new report instance
var report = new Stimulsoft.Report.StiReport();
// Load report from url
report.loadFile("../reports/SimpleList.mrt");
// Assign report to the viewer, the report will be built automatically after rendering the viewer
viewer.report = report;
// Show the report viewer in the 'content' element
viewer.renderHtml("content");
</script>
